As technology for cars has improved over time, the ignition keys have evolved too. The days of the simple mechanical keys you could purchase from a hardware shop for less than $10 are long gone. The newer models have computers that have improved anti-theft security. The cars require a transponder chip-integrated key to be programmed by a professional locksmith car dealer or mechanic for proper operation.
There are many kinds of car key programming that can be performed by professional locksmiths. Some are extremely complicated and may require advanced tools. These tools are generally not available to the general public and are used only by professionals. This kind of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other kinds of key programming can be performed by anyone. They are typically accomplished by using the onboard diagnostics port, that can be accessed using an instrument for programming keys. Locksmiths can carry out this method with the assistance of a guide online and the owner's manual.

Key Programmers
Modern vehicles often require a key programming process to start the system of the vehicle and allow the vehicle to start. In some instances, the key will need to be programmed by an auto locksmith or a dealer. The key might not function properly or not start the car in any way. This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive. This is why it's a good idea to always have two working keys for a modern automobile and have the replacement key programmed if necessary.
A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It can also clone the data from an existing key and allow duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They have diagnostic software that enables them to communicate with computers and also provide bidirectional interfaces to work with the immobilizer system.
There are a number of different kinds of keyprogrammers that are available, and they come in a variety of shapes and sizes. Some are inexpensive, while others could cost thousands of dollars. Some are designed for specific kinds of vehicles and provide advanced diagnostics for the car's electronic systems.
Consult your owner's guide to learn how to program a key for your vehicle. Some manufacturers use proprietary technology that guarantees that the dealership is the only entity able to create new keys, however other manufacturers make it easy for anyone to accomplish it themselves.
If you're unable to program the new key by yourself, then you can request your dealer to do it, but it'll be very costly. Another option is to buy a keyprogrammer online. They're less expensive than going to the dealership however, they're not cheap. Before purchasing one, do some research on the seller. Some aren't reliable and could cause damage to your vehicle.
Transponder Chips
If your car was manufactured in the last 20 years, chances are it contains a transponder chip within of it. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your car.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This stops the vehicle from being started by hot-wiring or tampering. The chip in the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is housed in the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a regular standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get received by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding siren. This system is designed to deter people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and committed thief might be able get around this system using a special device to intercept the signal.
As you can see there are quite a number of benefits to having a transponder key. This is something that all vehicle owners should think about if they are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the car remotely, emit chirping sounds to help locate cars, or turn on the heated steering wheel. A lot of these features may appear convenient however they could make it more difficult to keep track of your car keys.
Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted by a small antenna inside the middle of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your car. You may be able to do it yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the vehicle that it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob and then it opens or closes the car's door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to function.
Once the car is linked with a specific fob, it will only accept signals from that specific device. In turn, other fobs won't be able to work with the vehicle, even though they appear similar. This is to safeguard the integrity of the vehicle's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
Most dealerships with newer cars will only deal with cars with original fobs, or genuine replacements supplied by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that is only available in the dealer service department. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems, can be programmed without the need for a dealership.
